FIELD OF THE INVENTION

The present application relates to a personal care composition, and, more particularly, to a personal care composition comprising a conditioning and/or styling copolymer for a keratin substrate of hair and/or skin origin.

BACKGROUND OF THE INVENTION

Undamaged virgin hair is smooth and shiny; its cuticles on the surface of the hair lie down smoothly making the combing easy. The hair surface is also hydrophobic in nature preventing excessive water absorption during washing. When the hair is either mechanically or chemically damaged through bleaching, perming or coloring, the hair surface becomes rough and frizzy and difficult to detangle and comb. As the hair surface becomes more hydrophilic, the resulting hair fibers swell during washing, making the hair even more difficult to comb.

Current conditioning and/or styling systems for regular and damaged hair generally use one or more combinations of cationic surfactants, amphoteric surfactants, silicones, fatty alcohols, polyquaterniums, amino acids, proteins, lipids and humectants. Wet conditioning of regular or damaged hair is accomplished by neutralizing the anionic charge of the hair by positively charged surfactants and polymers and creating a hydrophobic layer from surfactant and polymers. This hydrophobic layer results in a reduction of the swelling of the hair fibers by making the hair more hydrophobic and reducing friction of the hair fibers. An overall result of wet conditioning is improved detangling, manageability and soft feel of the hair. Upon treatment with cleansing systems like shampoos, 2/1 shampoos, body washes or shower gels, the combing performance, detangling properties, hydrophobicity of the hair and lubricity are not maintained sufficiently.

Further, certain aspects of the present invention are illustrated in detail by way of the following examples. The examples are given herein for illustration of the invention and are not intended to be limiting thereof.

Example 1: Wet Combability

The combing measurement of the hair tresses treated with conditioner was done on a texture analyzer (FIG. 1) without manually detangling the hair. The energy needed to comb the tress was listed as gf-mm. For every measurement, 3 bleached hair tresses were used and the average was calculated. To measure durable conditioning the tress was first treated with 0.2 g/g hair conditioner, which is then rinsed off and the comb energy is measured. After the measurement the hair is washed with non-conditioning shampoo once, comb energy was measured then 3 and 5 times. No conditioner was applied in between.

From FIG. 2, it is demonstrated that chassis is provided good initial conditioning properties, but it is also evident that cationic surfactants do not provide long-lasting conditioning. The Chassis consist of cationic surfactant and fatty alcohol. Adding 1% homopolymer PolyAPTAC to chassis has provided excellent long-lasting conditioning. It has outperformed commercial example containing cationic polymers.

Example 2: Wet Combability after Multiple Washings

The Terpolymers provided even improved durability compared to homopolymer/s. Also the initial wet comb energy values right after the application was much lower. There was no significant difference between the different types of terpolymers. From the results (FIG. 3), it is apparent that the conditioning performance of terpolymers after several washes with silicone-free shampoo is even improved compared to cationic homopolymer (PolyAPTAC). The conditioners were applied on damaged hair 0.2 g grams per gram of bleached hair (1 hour bleached) and wet comb energies were measured after 1, 3 and 5 times of washing with 0.1 grams per gram hair shampoo (shampoo: 12/2 SLES/CAPB).

Terpolymers can be applied to shampoo applications, as well. FIG. 4 presents the wet comb energy after 1 and 3 shampooing. Terpolymer has clearly outperformed commercial referencing sample and shampoo containing cationic Guar, which is typically used conditioning polymer in various shampoos. The wet combability test results are provided in Table 1.

Example 3: Hydrophobicity Determination by Contact Angle Measurement

Contact angle is the indication of the surface hydrophobicity of hair. The immediate and long-lasting hydrophobicity of the terpolymers were studied by measuring the contact angle after several washes with a clarifying shampoo. The method is as follows: (i) A portion of the hair tress was stretched on a specially designed plate so that the fibers were suspended together in space to form a “single” surface (ii) A droplet of Deionized water was delivered from a syringe onto the fiber surface. Droplet mass is ˜0.008 g, (iii) Images were collected at intervals of 1 s or 10 s.

The higher the contact angle the more hydrophobic is the surface. The undamaged virgin brown hair is naturally hydrophobic, but all the chemical treatments such as bleaching reduce the hydrophobicity of the hair. Contact angle of virgin hair is about 110 which is reduced to 85 by bleaching. Also the water droplet applied to the hair surface is absorbed in 60 s. On virgin hair, the droplet can stay several hours. The results demonstrates (FIG. 5) the influence of different (1 wt %) terpolymers supplied from a conditioner on the contact angle. It is concluded that the treatment with terpolymer containing conditioners were able to retain the hydrophobicity of the damaged hair close to the level of virgin hair. The hydrophobicity test results are provided in Table 2.

Example 4: Sensory Evaluation

A trained panel of experts has evaluated the sensory properties of the treated hair tresses and the results were very much correlating with measured values e.g. comb energy values. Sensory properties are essential part of consumer acceptance. With the help of the sensory evaluation the long-term properties after multiple uses can be determined.

Terpolymers were used at 0.2 wt % active in conjunction with 12 wt % SLE₂S, 2 wt % CAPB with water added to 100%. The simple shampoo formula was then applied to the hair at 0.3 g/g bleached Caucasian hair and washed and rinsed off. After drying at RT, it was evaluated. Then the procedure was repeated 4 more times and the samples were evaluated. The following test shampoos and market reference shampoos were compared with terpolymers of the present application for the sensory evaluation (Table 3).

At wet state all the tested terpolymers in the shampoo clearly outperformed commercial non-silicone containing shampoo and efficacy got improved after several washes. At the dry-state after multiple washes shampoos based on the terpolymers outperformed the commercial example. The wet and dry stage sensory evaluations are provided in Table 4 and Table 5; FIG. 6 and FIG. 7.

Example 5: Procedure for Determining the Cationic Charge Density of Polymers

To determine the cationic charge of polymers, a Miltek charge analyzer was used. The aqueous sample was placed in the measuring cell. Once the PCD was turned on, the piston of the cell oscillates and causes a high flow rate. Any charged material adsorbed to the cell wall was separated from its counter-ions by the flow to create a streaming current. Two electrodes in the cell pick up this current and display it. The titration module automatically selects the titrant which is charged oppositely to the sample (cationic sample-anionic titrant) and adds it to the sample until 0 mV was reached. As a result the consumption of titrant in ml was indicated on the display as well as the charge demand in meq/1.

Example 6: Wet Combability of Sulfate Free Shampoo Composition

The combing measurement of the hair tresses treated with sulfate-free shampoo was done on Instron device. The energy needed to comb the tress was listed as gf-mm. For every measurement 3 bleached hair tresses were used and the average was calculated. To measure durable conditioning the tress is first treated with 0.1 g/g hair shampoo, which is then rinsed off and the comb energy is measured. The tress was washed 2 more times and the comb energy was again measured. The results of wet comb energy after 1 and 3 washes are disclosed in FIG. 8 for sulfate free shampoo compositions of Table 6.

From the results of wet combability of Sulfate free shampoo compositions, it is evident that the conditioning performance of terpolymers in sulfate-free shampoo is even better as compared to PolyAPTAC, a cationic homopolymer. The shampoos were applied on damaged hair 0.1 g grams per gram of bleached hair (1 hour bleached) and wet comb energies were measured after 1 and 3 and 5 times of washing with 0.1 grams per gram hair experimental shampoo. Both homopolymer and terpolymer containing sulfate-free shampoos were outperforming commercial silicone-free shampoo. When compared to the silicone-containing commercial sulfate-free shampoo, the experimental shampoo was performing on the same level even without silicones.

Example 7: Durable Styling Properties of Conditioning Polymers on Frizzy Hair

The durable styling properties of following conditioning polymers were evaluated on frizzy hair:

-   -   i. APTAC Homopolymer: (Poly-APTAC)     -   ii. APTAC based terpolymer: A 16522 (APTAC/AA/BEM)     -   iii. Hair spray containing Styleze XT3     -   iv. Commercial Available hair spray (heat activated)     -   v. 3% polymer solution of each polymer is prepare and is tested.

The Hair tresses treated with above mentioned formulations are evaluated according to the protocol which is presented below. Originally it was developed to study styling durability of Styleze XT3. Wherein, the use of Styleze XT3 in hairstyling products provides benefits for different hair types such as curly, wave and frizzy hair. The polymer is activated after heating by a hair straightener and concentrates on the damaged parts of hair to improve the softness, frizz and shine. With the same technology, commercially available hairspray is a heat-activated formula with keratin protein. This semi-permanent styling spray is claimed to transform curly, frizzy hair into a straight, smooth style that lasts up to 3 washes.

Tress Treatment Method:

Materials Required:

-   -   i. Shampoo; Normal—non care/conditioning     -   ii. Conditioner: Normal     -   iii. Tress type: 1″ or 1.5″ width×6.5″ length mulatto (2 g and         3.5 g, respectively).     -   iv. Blow dryer: Professional.     -   v. Vent brush     -   vi. Flat Iron: 1″ wide, high temp setting (>/=205°         C.)—preferably need to deliver sustained heat (>145° C.) to the         hair fiber assembly (it has been observed that the temperature         realized on the hair is approximately 40-50° C. lower than the         iron setpoint—dependant on the rate of movement). Iron setpoint         of 232 C preferred for optimal results.

Method:

Hair tress was washed with warm water (35-40° C.)—30 second wetting, 30 sec wash, 30 sec rinse. The excess water is removed and blot with towel—tress in damp state. Approximately, 0.30 g of product/gram of hair was applied; worked through from root to tip with fingers until uniformly distributed—remove excess with fingers or comb. The tress was straightened by Blow dry (high heat) with slow uniform motion from root to tip with vent brush. It was ensured for alignment of fibers prior to next step. Flat iron root to tip with 4 to 5 passes, ˜1.25 in/sec. Wherein, the hair should feel smooth and natural with good shine, and if there is any raspy polymeric feel, additional passes were allowed. Tress was allowed to equilibrate to lab conditions for 30-45 min at 25° C./40% RH. Tresses were evaluated for their straightness. Hair tresses were washed with warm water of 35-40° C. with 30 seconds wetting, 30 seconds wash (normal shampoo), and 30 seconds rinse. Further, condition the hair for 30 seconds, followed by 30 seconds rinse. The hair was dried with diffuse hot air (dome dryer). The hair tresses were allowed to equilibrate to lab conditions for 30-45 min at 25° C./40% RH. The tress was evaluated after one wash. In the similar manner, repeat steps for 7 to 10 times as desired.

From durable styling experimental results (FIG. 9 to 12), it is very evident that the polymer solutions containing either homopolymer or terpolymer (A16522) outperformed commercial hair sprays designed to provide durable styling. Both test products showed visibly a good performance. Frizzy hair is transformed into a straight, smooth hair. The frizz was thus reduced significantly. For long lasting effect (durability) the composition of this invention is better than commercially available analogous after multiple washes.

Example 8: Stiffness/Flexibility Evaluation of Conditioning Polymers on Hair

Stiffness is defined as the resistance to being crushed. A stiff styling product would be one that requires a high force in order to cause a deformation. The stiffness/flexibility of the homo and terpolymers were measured at 50% RH. A set of 6 tresses were used for every sample. It is observed that the homo and terpolymer containing APTAC provided significantly lower stiffness as compared to that of references products or polymer (Table 7). The higher stiffness is associated with stronger hold.

TABLE 7 Stiffness/Flexibility of Homopolymers/Terpolymers Product Average Stiffness (F1) Std. Dev. APTAC Homopolymer 86.49 27.43 Terpolymer A 16522 74.80 8.15 Commercial Mousse A 188.65 55.59 Commercial Mousse B 316.78 61.28 (Reference)

Example 9: Resilience Evaluation of Conditioning Polymers on Hair

Resilience is the maintenance of stiffness on repeated deformations. So when looking at the stiffness data, the closer the ratio is to one for a sample, the more resilient the product. It means that the duration of a curl hold stiffness of a product is better. Hence, the developmental polymers showed a better result than the references and it is significant (Table 8). The stiffness retention of both test polymers is almost the same.

TABLE 8 The average resilience of Homopolymers/Terpolymers Product Average Resilience Std. Dev. APTAC Homopolymer 1.05 0.01 Terpolymer A 16522 1.05 0.04 Commercial Mousse A 0.86 0.02 Commercial Mousse B 0.69 0.06 (Reference)

Example 10: Plasticity Evaluation of Conditioning Polymers on Hair

Plasticity is defined as the ability of a material to bend without breaking. The plasticity of the homo and terpolymers of present application is as good as the references products (Table 9).

TABLE 9 The average plasticity of Homopolymers/Terpolymers Product Average Plasticity Std. Dev. APTAC homopolymer 1.10 0.02 Terpolymer A 16522 1.11 0.02 Commercial Curl Power Mousse A 1.10 0.02 Commercial Mousse B 1.10 0.02 (Reference)

Example 11: Elasticity Evaluation of Conditioning Polymers on Hair

Elasticity is defined as the ability of a material to bend without breaking and return to the original shape without using an external force. Test polymers performed better than reference, i.e. Commercial Mousse. Terpolymer A16522 is slightly better than APTAC Homopolymer, but there was no significant difference in the performance (Table 9A).

TABLE 9A The average elasticity of Homopolymers/Terpolymers Product Average Elasticity Std. Dev. APTAC Homopolymer 0.78 0.09 Terpolymer A 16522 0.87 0.07 Commercial Mousse 0.54 0.12 Commercial Mousse 0.19 0.02 (Reference)

Example 12: Curl Retention Evaluation of Conditioning Polymers on Hair

This analysis indicates the holding power of a styling product. A set of 8 tresses is used for every sample. The curl retention of the test polymers is measured based on following parameters:

-   -   i. Temperature: 25° C.±2°     -   ii. Humidity: 50%±2%     -   iii. Time: 4.5 hours         Wherein, the test polymers showed better results than reference         group wherein no polymer was employed but the results were not         better than Commercial Curl Power mousse. Curl retention of         Poly-APTAC was better than terpolymer A16522 with the confidence         interval at 95%. After 4.5 hours, the curl retention of         Poly-APTAC is 70% and terpolymer A 16522 60%.

Example 13: Shine Evaluation of Conditioning Polymers on Hair

Shiny hair is a healthy sign. Therefore use of polymers in hair styling products is available to increase the shine of hair by forming a film around the surface of hair. Such polymers increases the luster values of hair after treatment and it can be calculated as the difference between specular and diffuse reflectance. The shine capability of products was measured. Set of 4 very dark European Caucasian virgin brown hair tresses was used for every sample. The luster calculation is given below:

$L_{Stamm} = \frac{S - D_{Stamm}}{S}$ $L_{Robbins} = \frac{S}{D_{Stamm} \times W^{1\text{/}2}}$

-   -   S=Area under Specular reflectance curve     -   D_(Stamm)=Area under Stamm type Diffuse reflectance curve     -   W½=Width of Specular peak at ½ its maximum intensity

The Lustre value is comparing the contrast between the dark region and the light region. The Peak Maxima is an indication of the brightness of the light portion of the tress. W½ is the width of the specular peak at half of its maximum intensity or the light area. Further the shine is evaluated and described by the Intensity, Stamm Luster and Robbins Luster values. Studies were conducted for (i) homo and terpolymer of APTAC; (ii) A commercial reference polymer; (iii) VC713 based mousse, a reference polymer. From our results, it is observed that the use of APTAC based polymers is better than reference polymer in providing gloss for hair stresses. The results are discussed in below Table 10-13 and FIG. 16-19.

Materials:

The medium density platinum bleached hair (6″ length) from International Hair Importers was procured. The hair tresses were cut to 0.5 inches in width and weight approximately 2.97 grams. Wherein, textures and tones permanent hair color (Shade 4R, Red Hot Red) was measured using HunterLab Colorimeter.

Hair Dyeing Procedure:

Dye 1″ hair tresses for 45 minutes at 71 F; rinse each hair tress for 2 minutes under running water. The APTAC/AMPS/PEG-BEM terpolymer was employed for evaluate its ability to protect the dyed hair color with various evaluation parameters that are known in the prior art for a person skilled in the art.

Interpreting the Results:

Color measurements (L*, a*, b*) were taken on each tress right after dyeing. L*, a*, b* values were measured on each tress after one, three, five and ten wash/treatment cycles. These values were compared to the initial L*, a*, b* values for the tress, and ΔE* was calculated for each tress. Each tress served as its own control. 10 measurements were taken for each tress. ΔE* was calculated based on the initial value of the tress. The ΔE* reported is the average ΔE* for 3 tresses. The smaller the ΔE* value, the smaller the color change, and better the color protection.

It should be noted that the terpolymers are meant to be used in combination with other cationic ingredients. For that reason, we tried the color protection performance in conditioner bases that are mimic finished formulas and also tried the performance of the terpolymer in finished commercial formulas. Commercial available compositions typically comprise a combination of alkyl quaternary compounds such as cetrimonium chloride, behentrimonium chloride to provide conditioning benefit, and silicones such as dimethicone to provide conditioning and color protection benefit. Therefore, it is important to assess the effect of the terpolymer in the presence of cationic polymers and silicones, as this will be a good indicator of its performance in finished products.
